Abstract: Red raspberries, as an excellent source of dietary antioxidants, were investigated for their effect on oxidative stress in healthy adults. Study 1 measured effects of chronic exposure in a parallel, multi-dose intervention. Subjects consumed one-cup red raspberries (1cR) daily for two-weeks, then were randomized to consume 1cR, 2cR or 4cR for additional two-weeks (n=8, by group). There was a reduction in TBARS, indicating a decrease in lipid peroxidation, after two-weeks of intervention in the 1cR group, but effects were not significant at week 4, or for other treatment groups. Study 2 measured effects of acute exposure using a cross-over design. Subjects (n=8) consumed single treatments of 1cR, 2cR, 4cR, bread and bread plus vitamin C. Post-prandial oxidative stress responses were complex and appeared related to calorie and antioxidant load. Overall there was no clear relationship between red raspberry consumption and protection against oxidative stress.
